IMPROVEMENT IN THE MANFACTURE OF RUB-IRONS FOR CARRIAGES.

Specification forming part of` Letters Patent N0. 136,857, dated March 18, 1873.

all.

To all whom it may concern:

Be it known that I, HENRY W. OLIVER, J r., of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Blank or Bar for Rub-Iron and I do hereby declare the following to be a `full, clear,`and exact description thereof, reference being had to the accompanying drawing making part of this specification, in which 1 Y Figure l. is a view in perspective ofthe bar from which the blanks are cut, and Fig. 2 is a like view of the blank ready for use.

Like letters of reference indicate like parts in each.

Previous to the date of this improvement the rub-irons for wagons were commonly 'made by bending a short iron plate along at or near the middle line, to the form of a common angle-iron. In the yuse of such irons the wear comes directly on the angle, and there being no excess of metal at that point, it soon wears through, and the Whole of it is then valueless, except for old scrap. The metal of the plate on either side of the angle is of no value'inI the use of the device except as a means byfwhich to fasten it to the wagon. Angle-iron has also been used for the same purpose,'butit was open to the same objection. Also, in bending the plateor rolling the angle-iron, it has l been necessaryr to have the met-al of the plate extend out a considerable distance oneithr side of the angle, whereas, for the purpose of fastening, a plate on one side is sufficient.

After various eiorts I have succeeded in.

rolling a bar having a longitudinal sectionof sufficient width to serve as a means of fastening the iron to the Wagon, and with a beadedflange along one edge, which, by its excessof metal, presents a durable wearing angle, and

at the same time saves the metal which heretofore has formed the other plate or halt` of the rub-iron.,` l y YTo enablevothers skilled in the art to make and usemy invention, I will proceed to describe its construction.

The bar B is rolled in suitably grooved y rolls, with a at part,b, comparatively thinmerely thick enough to provide a` secure means by which the iron' can be fastened to the wagon. At the same time I roll along the upper side of one edge a narrow flange, a, and on the outside of this narrow flange I roll a bead, s. The bead s is a practical and Valuable addition to the metal, which would other- Wise remain along the line of junction of the angea and part b, and by the amount of its thickness is an improvement on the rub-iron made from a bent plate or the ordinary angleiron. I also dispense with that partof the ordinary rub-iron which extends above-the liange aat right angles to the part b. This bar is then out into suitable lengths, as' at b', and

screw or nail holes dd being punched or drilled,

it is ready for sale or use.

hat I claim as my invention, and desire to secire by Letters Patent, is-

1. A wrought-iron bar, having a iiat longitudinal part, b, a narrow flange, a, at right angles thereto, and a bead, s, at the angle outside the flange, substantially as described.

2. An angled rub-iron, b', having a bead, s, onv the outside of the angleA at the point subject to wear, substantially as set forth.

In testimony whereof, I, the said HENRY W. OLIVER, Jr., have hereunto set'my hand.
